A ce moment-là, le micro-ordinateur (271) demande des informations concernant une capacité de charge stockée, une tension de charge mesurée par un détecteur de tension (258), et une capacité de charge standard, en tant qu'informations provenant d'un micro-ordinateur, (252) et acquiert ces informations par l'intermédiaire d'un circuit de communication (254) et d'un circuit de communication (272). Le micro-ordinateur (271) détermine une capacité de charge réelle à partir de la tension de charge mesurée reçue et la compare avec la capacité de charge stockée. Si un résultat de comparaison montre qu'une valeur seuil est dépassée, et que la tension de charge est inférieure à une autre tension seuil, la capacité de charge est mise à zéro. Cette invention permet une correction précise d'une capacité de charge.
